2.It adopts a fully electronic controlled positive flow hydraulic system with independent programming technology, matched with an HPR300 large-displacement main pump, and the output torque is 7% better than that of competitors. The system achieves a perfect match between load and flow, cancels the traditional priority logic valve, reduces pressure loss, and makes the control response faster and the action more precise. Whether it is continuous excavation or precise unloading, it can achieve an efficient and convenient operating experience and greatly improve work efficiency.

3.In terms of reliability, self-lubricating copper-based alloy sleeves are used at key joints, which effectively reduce wear and significantly extend the service life of the equipment. The overall structure of the machine is reinforced, and combined with the crawler travel mechanism, it has super strong terrain adaptability, can work flexibly in complex terrains such as mines and mountains, ensures stable performance under high-intensity operations, and the attendance rate is far higher than the industry average.

4.In terms of humanized design, the cab has a wide space and is equipped with air-suspension seats as standard. Combined with low-vibration and low-noise optimized design, it greatly reduces the work fatigue of operators. The full-view driving environment complements the precise control system, making long-time operations easier, fully reflecting the humanistic care for operators, and further improving operational safety and efficiency.
